udf for transient mass flow rate inlet
I am trying to figure out how to write a udf for applying a transient mass flow rate at the inlet. In my case study the mass flow rate varies with time from 0 to 40L/min and then comes down to zero in one cycle that ranges from 0 to 4 sec.

If anybody have a ready made udf, i wud be grateful if u could plz post it in this link or pass on through my email id.

I admit i have a bad programming knowledge but since it is bit urgent, i have to seek ur opinion and help without having to take the pain to learn it myself.

Plz do help
